Organelles
Separates the cell from its external environment, is selectively permeable (controls what goes in and out), protects the cell and provides stability.
What is the cell membrane?
The phase where the cell grows, DNA replicates, and the cell prepares for mitosis.
What is Interphase?
Phase where chromatin tighten and coil to become visible chromosomes.
What is prophase?
In 1665, he became the first to observe cells.
Who is Robert Hooke?
A substance capable of causing cancer.
What is a carcinogen?
Referred to as the "powerhouse" of the cell, and is responsible for creating energy for the cell.
What is mitochondria?
The time it takes to complete the cell cycle.
What is 24 hours?
Phase where sister chromatids are pulled apart to opposite poles of the cell.
What is anaphase?
These cells lack a nucleus and membrane-bound organelles.
What are prokaryotic cells?
Most common carcinogen for skin cancer.
What is radioactivity and/or ultraviolet light?
The "control center" of the cell, and is responsible for cell metabolism and reproduction.
What is the nucleus?
Uncontrolled cell division due to mutations in cell cycle can result in __________.
What is cancer?
Phase where chromosomes align at the equator or middle of the cell.
What is metaphase?
Considered the basic building blocks of all living things.
What are cells?
Common carcinogen for lung cancer.
What is tobacco?
The "factories" in the cell that produce protein.
What are ribosomes?
The second stage of the cell cycle.
What is prophase?
After mitosis, where the cytoplasm of the cell divides to form 2 daughter cells.
What is cytokinesis?
This type of cell has a diameter between 10 to 100 micrometers.
What are plant cells?
HPV is a _________ associated with cervical cancer.
What is a virus?
Fluid filled organelles that store materials such as food, water, sugar, minerals and waste products.
What are vacuoles?
These can halt the cell cycle if needed so that cells can divide at a controllable rate.
What are checkpoints?
Phase where chromosomes uncoil to reform chromatin.
What is telophase?
These cells contain a nucleus and organelles.
What are eukaryotic cells?
Elevated estrogen levels in women is a risk factor for _________.
